I've been struggling to find a decent lightweight terminal for a while, actually. I used to happily use aterm, but was losing a fair bit of information because it did not handle unicode chars. I then switched to lxterminal and now urxvt-unicode, but the trouble I'm having is that whenever the windows get resized by the wm the terminal either goes completely blank or loses some lines or does something or the other similar in a completely random way. I think it's time to get a new terminal app that is lightweight and at the same time does not exhibit these kinds of random behaviour.

Just curious as to whether or not you're still having problems with this. I've been having problems with rxvt-unicode not properly changing line wrapping on resize. On rare occasions I'll have a window open where it does in fact resize correctly, but almost all the time it does not, and I know this worked correctly for years:
